PS288 Owner’s Manual 4—3
FlashCORE programmers on the PS288 are made up of the following com-
ponents:
CPU - PowerPC Controller Board (RPX-Lite)
The PowerPC Controller Board is based on MCP850 PowerPC CPU and
includes many hardware elements, like 10 Base-t Ethernet port and a
PCMCIA interface.
It has a memory controller that allows the device programming algorithm to
control the bus cycle timing for the memory range used for programming.
The onboard I2C bus is used to address a serial EEPROM on the adapter
board of the programmer to collect statistics on a given socket. The I2C bus
is also used on the RPX Lite Board to address the temperature and thermal
monitor (STTM) and another onboard serial EEPROM used for RPX config-
uration storage.
Waveform Board
The core of the FlashCORE programmer design, the Waveform Board inter-
faces to the PowerPC Controller Board with two programmable logic
devices: a CPLD (non-volatile) and a FPGA (volatile). These two logic
devices make up the basic programmer control circuitry. The CPLD contains
logic to control the communications interfaces as well as the analog controls
of the programmer and configuration of the volatile FPGA. The FPGA is
used to route address, data and control signals from the PowerPC to the
devices in socket, and provide Device Insertion, V
PP
waveform generation,
and Self-test circuit control logic.
Backplane Board
The Backplane Board is a connection scheme to connect the Waveform
Board to the Socket Adapter board. In addition to supplying connections
between the two boards, it also supplies the circuitry for address line buffer-
ing to isolate each device so that a failing part cannot affect non-failing
devices and power and ground switching relays.
Socket Adapter Board
The Socket Adapter Board connects to the Backplane Board to supply the
electrical connections for programming to the individual sockets. It also con-
tains a 10 bit ID bus used to identify the adapter installed. A small EEPROM
exists on this board for maintaining socket cycle counts for this physical
adapter. By putting this EEPROM on the adapter itself, the socket cycle
counts for a specific Socket Adapter Board can be tracked independent of
the FlashCORE programmer it has been installed on.
In each FlashCORE programmer, there is a PCMCIA card that acts as the
local drive for the FlashCORE programmer. There are various sub-directo-
ries and files on this, as shown in Figure 4-2.
Power to FlashCORE programmers is provided by a universal power supply,
which powers two FlashCORE programmers.

Each programmer is connected to the 16-port network hub via a UTP cable
with RJ45 connectors at both ends. The network hub is also connected to the
Handler Computer, which communicates to all FlashCORE programmers
during the device programming process and when running diagnostics tests
on a FlashCORE programmer.
Computer
System
The computer system of the PS288 consists of the Handler Computer and
various networking components that allow the Handler Computer to com-
municate with the FlashCORE programmers.
Handler Computer
The Handler Computer operates using the Microsoft
®
Windows XP operat-
ing system and the client network communications. It hosts TaskLink and
the AH500 operating software, as well as several subsystems within the
machine including:
• Vision system and software
• PNP head motion control system
• Label marking system
• I/O Controller interface
The Handler Computer communicates with the network by a 10BaseT Ether-
net connection, and contains mappings of all the major disk volumes used by
the network. Any data transfer required from a major network volume can be
accomplished on the Handler Computer using Windows
®
Explorer.
The PS288 user interface (AH500 software) is run from the Handler Com-
puter. It contains all graphic components that the system operator uses dur-
ing normal operation, including option configuration, programmer setup,
and system adjustments.
The vision interface card is installed in the Handler Computer, as well as its
operating software. This system is run in conjunction with the AH500 oper-
ating software to ensure proper alignment of programmable devices before
being placed into the programming sockets.
The motion control system interface allows the AH500 software to commu-
nicate with the PNP head gantry system. Movement commands and posi-
tional feedback are provided to the AH500 software with this system.
The Handler Computer and AH500 software communicate with the label
marking system via serial port on the rear of the Handler Computer. Label
data transfer and labelling system responses are sent to and from the label
marking stage through this connection.
The I/O Controller interface determines the condition of the various sensors
and systems located throughout the PS288 as reported to the I/O Controller.
These conditions are then read by the AH500 software to determine the state
of the machine before issuing system commands. See Appendix A, “I/O
Controller LED Status.”

User Interface
System
Operator interaction with the PS288 is achieved with the following equip-
ment:
• Touch screen monitor
• Keyboard and touchpad
• Light tower
Through the use of these assemblies, the operator may communicate with
and control the PS288, as well as view system feedback and status indica-
tions.
Touch Screen Monitor
The touch screen monitor is a 30 cm (12 inch) LCD flat panel with inte-
grated touch screen. There are three cabled connections: DC electrical
power, a DB-15HD SVGA monitor connection, and a DB9 / RJ-45 connec-
tion for touch screen communications.
The 115 VAC supply is provided by the I/O Controller.
The RS-232 connection for the touch screen is plugged into the COM1 port
on the Handler Computer. The touch screen can be used in place of the
touchpad for operations or any other tasks that take place on the Handler
Computer. The touch screen does not work with the Laser Computer.
Keyboard and Touchpad
The PS288 uses an integrated keyboard and touchpad for space saving pur-
poses. The keyboard and touchpad are used as the central control mecha-
nisms for all systems on the PS288.
Light Tower
The light tower located on the top of the PS288 is used as a visual indicator
of the operating condition of the machine. It receives system status signals
from the I/O Controller:
Safety Systems
The PS288 employs safety systems to assist in the prevention of personal
injury, as well as potential damage to the equipment. Because of the speed
and force by which the PNP head moves, it is imperative that these safety
systems are operational and are never bypassed.
Emergency Stop and Safety Shield Interlocks
WARNING: Pressing an E-Stop button stops motion of the gantry
and PNP head only. It does not remove power from the PS288 or
the Option Bay (if installed).
Each of the safety shields found around the operating envelope of the PS288
has a safety interlock switch associated with it. When any safety shield is
opened during normal operation, gantry and SPNP head motion stops, and a
